Breathing tube patients in ICU tested for lung inflammation treatment
This trial studies whether changing immune cells in the lungs (using a procedure called MiniBAL) can improve outcomes in adults who are critically ill and on a breathing tube. It may help doctors better manage acute lung injury by targeting inflammation early in the ICU stay.
Denver, ColoradoAges 18–99 - NCT05773001RecruitingPhase 1
Study of an immune treatment for ozone-related lung inflammation
This early-phase study tests how an immune-targeting treatment affects inflammation in the lungs after ozone exposure. It may help researchers understand—and eventually reduce—lung inflammation triggered by air pollution.
Durham, North CarolinaAges 18–55 - NCT05745298Recruiting
Electrical and breathing therapy to improve unassisted cough after spinal injury
This study tests whether pairing electrical stimulation with breathing muscle training can help you cough without needing assistance. It’s for people recovering from a spinal cord injury within the last year, and who can safely feel and respond to the electrical stimulation.
Miami, FloridaAges 18 years+ - NCT05298748Recruiting
Audio recordings to help breathing control mature in preterm babies
This trial studies whether listening to special “womb” sounds can help a preterm baby’s breathing control develop as they grow. It may help babies who are already breathing on their own (with low or no extra oxygen support).
Cleveland, OhioAges 1 week–1 month - NCT05686850Recruiting
Noninvasive breathing support vs high-flow oxygen after ICU extubation
This study compares two breathing supports used after a breathing tube is removed in the ICU: a noninvasive ventilator (mask-based) versus high-flow nasal oxygen. It aims to see which one works better when patients develop breathing trouble soon after extubation.
BrusselsAges 18 years+ - NCT05684562Recruiting
Lung function and exercise capacity in Fontan patients
This study looks at how well the lungs and heart work together during exercise in people who have had the Fontan operation. The goal is to understand how lung function affects overall fitness, which can help improve care for Fontan patients.
AnkaraAges 8–55 - NCT05674643Recruiting
Gastric testing during children’s surgery
This trial studies how the stomach is working in children around the time of surgery. It may help improve how doctors assess and manage stomach function to make surgery safer and more comfortable.
Boston, MassachusettsAges 2–18 - NCT05655182RecruitingPhase 1/Phase 2
RSV vaccine study for infants and toddlers who may be at risk
This Phase 1/2 study tests an RSV vaccine (BLB-201) in infants and young children. It aims to see how the vaccine works and how safe it is, including in children who already have RSV antibodies or not.
La Mesa, CaliforniaAges 6 months–5 years - NCT05656105RecruitingEarly Phase 1
PET scan study of brain inflammation after COVID
This early-phase study uses a special PET scan to look for signs of brain inflammation in people with ongoing (long-term) nervous system symptoms after COVID-19. It may help researchers understand what is driving symptoms and whether this imaging approach can detect inflammation.
Birmingham, AlabamaAges 18–65 - NCT05500833Recruiting
Studying breathlessness in children to better understand symptoms
This study looks closely at why children feel short of breath (“dyspnea”) and how breathing symptoms change over time. Your child may help doctors improve understanding and care for breathing problems like asthma or other lung conditions.
ParisAges 6–17 - NCT05624450RecruitingPhase 3
Test drug tozorakimab for hospitalized viral lung infection needing oxygen
This Phase 3 study tests tozorakimab to see if it helps people hospitalized with a viral lung infection that is causing low oxygen levels. You might qualify if you still need supplemental oxygen when the study starts.
Birmingham, AlabamaAges 18 years+ - NCT05604430Enrolling by invitation
Study of pre-hospital breathing support with a specific ventilator
This study looks at breathing support given outside the hospital using a particular ZOLL ventilator model and software version. If you were treated with the right equipment, the team will use the ventilator’s recorded data to evaluate how ventilation was delivered.
Hartford, ConnecticutAges Any age - NCT05536076Recruiting
Breathing treatment to help recovery after spinal cord injury
This study tests whether a breathing-support treatment (for abnormal breathing during sleep) can improve breathing recovery in people living with a spinal cord injury. It aims to see if treating higher carbon dioxide levels and sleep-breathing problems leads to better breathing and recovery.
Detroit, MichiganAges 18–89 - NCT05440851Recruiting
Testing different treatments for severe breathing failure in ICU
This platform trial studies which treatment works best for adults with sudden, severe breathing failure needing oxygen or a breathing machine in the ICU. It may help patients by matching them to the most appropriate treatment strategy and tracking outcomes to improve care.
Tucson, ArizonaAges 18 years+ - NCT05427136Recruiting
Study early lung problems after childhood cancer treatment
This study looks for early lung (breathing) problems in children after certain cancer treatments, using lung tests and sometimes MRI scans. It may help doctors spot breathing complications earlier and guide better care.
BaselAges 4–22 - NCT05379673Recruiting
Breathing changes with extra oxygen after surgery
This study looks at whether giving extra oxygen during recovery from general anesthesia changes how you breathe after surgery. You may be offered different oxygen levels around the time you wake up to see what helps your breathing most comfortably.
Stanford, CaliforniaAges 18–70 - NCT05336760Recruiting
ALS study of swallowing comfort, quality of life, and PEG views
This study looks at swallowing problems in people with ALS and how they affect quality of life, including people’s attitudes toward PEG (a feeding tube). It may help researchers understand what support and information could improve comfort and day-to-day living.
LjubljanaAges 18 years+ - NCT05322785Enrolling by invitation
